In the selection of lost circulation material (LCM) it is very important to determine its shut-off capacity to the formation. The hole size changes with the formation so the particle size of LCM must be selected. This instrument is used to help evaluating the LCM. It can simulate different formation effectively using different sized cracks and bed and can evaluate the shut-off efficiency and volume of leakoff before the seal.
This instrument is made in accordance with API recommend practice and a plugging pressure backing device is added aims to checkout the pressure needed for damaging the plugging zone and research the structure strength of LCM. In addition, this instrument is easy to operate and has small volume and simple structure. It can simulate leakoff parameter of different situation.
